ATTACHMENT FOR VEHICLE-SPRINGS.

To all whom it may concern: Be it known that I, Gnome S. Srnnvnu, a citizen of the United States, residing at Canon City, in the county of Fremont and State of Colorado, have invented new and useful Ii'nprovements in Attachments for VehicleSprings, of which the following is a specification.

This invention relates to improvements in attachments for vehicle springs and more particularly to the type known as elliptical springs. 1

One object of the invention is the provision of a device which may be permanently associated with the spring and perform the function of an auxiliary spring.

Another object is the provision ofa device i which may be employed for repairing a broken spring, the device being so constructed that it may be secured adjacent to the break in a spring and when so positioned will cpuple the brblien sections together and by virtue of itsconstruction, a broken spring {body to whieh the device is ap )lied .will suiter no loss of resiliency.

Vith these and other; objects in View, which will-more fully hereinafter appear, the present invention cinp ists in certain novel details of construc'io and rrangement of parts, hereinaft r fully described, illustrated in the accom a ying drawings and more particularly pointed out in the appended claim.

In the accompanying drawings, forming a part of the specification; -Fig. 1 is a side elevation'of a portion of the. medial pontion of a semi-elli nical spring with myiimproved device applied thereto. Fig. is a plan view of the device as shown in *ig. 1. Fig. 3 is a detail side elevation of the "device removed from thefposition shown in F 1gs. 1 and 2.

Fig. 4 a side elevation of one end portion of a vehicle spring after the same has been broken at the clip and showing my improved device in side elevation; and applied to the clip and spring. Fig. 5 is a modified form of a repair device, employed for connecting the sections to a full elliptical spring. Fig. is an end view of the same. 7

Similar numerals of reference are employed to designate corresponding parts through out.

Asshown in Fig. 1 the vehicle spring to" which my device applied comprises a plurality of leaves designated by the numeral 5,

the said spring being connected to an axle G by means of the usual axle clips 7. The auxiliary spring device forming the subjegt matter of the present invention comprises a plurality of superimposed and substantially semi-elliptical leaves designated by the numeral 8. The leaves 8 are substantially of the same length and are fixedly secured together at their media]. portions by means of a bolt orrivet 9 passing through .alining openings formed in the leaves. The

device'thus formed will be considerably less in length than the length of a. semi-elliptical spring; as clearly shown in the drawings.

It will be observed by reference to Fig. 3 that the opposite ends of the leaves 8 are normally spaced from each other a slightdistance so that When the ends are-clamped together upon the vehicle spring, the said leaf ends will form resilient and yielding auxiliary spring ends, whereby, when the auxiliary spring is clamped in position upon the broken vehicle spring, the original resiliency and supporting strength will berestored thereto.

The uppermostleaf in the device terminates at one end in an upturned extension 10, and at its opposite end terminates, in an eye 11, the said eye 11 extending beyq nd the adjacent ends of the leaves 8. When the device is employed to r pair a semi-elliptical spring broken at its ,pedial portion, as shown in F ig, l, the deaice arranged on the concaved surface {it the spring 5 and so arranged that its curye will extend reversely to the curve of the spring 5. {Fine device adjusted to straddle the broliwn prong of the spring and "when properly positioned issec ured in place by clamping devices which in the present in stance are shown to include plates 12 and 13 of greater length than the widths of the device and spring 5 to which it is applied. The plates 13 are arranged transverse the convex surface of the spring 5 and on either side of the break thereof and in alinement with the opposite end portions of the device, while the plates 12 arearrangcd transverse the device adjacent to its opposite ends, as shown in Fig. 1. 'The opposite end portions of the plates 12 and 13 are provided with openings for the reception of bolts 14- in- .sertible through the openings, the said bolts being provided at one end with heads 15 to bear on the plates 12, while their opposite end portions are threaded to receive nuts l6-to 'bear on the lower faces of the plates 1 13. With this construction it will be man1-- fest that by turning the nuts 16 after the bolts have been positioned that the device and spring 5 will-be firmly clamped be twe'enthe plates 12 and13.

' In positioning the plates on the device one of said plates is arranged .to bear on the inner surface of the extension 10, while the metal corresponding plate at jace'nt 'to the .eye 11. It will be manifest, owing tothe leaves being'secured only at their medial portions that the resiliency of the devices will be increased over a structure in which the leaves 8.were welded together. throughout their lengths or if the a single piece of bolt 18 is passed through the eye 11 at one end of the device, while the opposite end portion is clamped to the springbody by bolts 19 and plates 20 and 21, in the manner before described. It is to be noted that, in this instance the weight of the vehicle body Will-force the eyed end of the upper leaf downwardly causing the terminal ends of all the leaves to move in close engage-- ment with each other, thus forming a spring end equal to the original. I

' In Figs. 5 and 61 have shown a modified form of the device employed for'repairing a break in a full elliptical spring when the said break occurs at either end of said when the straps are the opposite end is positionediaddimensions to the of straps designated by the numerals 22 and 23 the said straps being oflset at 'their medial portions, the spaces between the opposite ends of the straps will be diiferent united by bolts 24. One of the bolts 24 is adapted to be inserted through the opening at the'end of one side spring. In this connection I employ a pair ofthe spring, while the opposite bolt re- I ceives. the eye 11 of the device, the latter being secured to spring in the manner before described.

From the foregoing, 'it is evident that I haveprovided adevice which is comparas rnple 1n structure and inexpensive tively in manufacture, embodying few parts and these' so ,ar'r'an'ged that the danger of dethe opposite side'of the rangeinent will be reduced to a minimum.

I claim z A device for repairing elliptical springs including an auxiliary spring consisting of a plurality of superimposed semi-elliptical leaves of a corresponding length and shorter than the said vehicle spring, the said leaves loosely bearing oneupon the other and riveted together at their central portions, the terminal portions of the leaves being nor- 'mally spaced apart so that when clamped together they form aresilient spring end, the upper of said leaves terminating at one end in an upturned extension and provided at its opposite end with an eye, and means adapted to bear on the upturned extension and passingthrough the'eye for securing the ends of the auxiliary spring on opposite sides of the line of cleavage ture in' presence of two witnesses."
